SHOW-WIN DOW STRUCTURE.

Application filed July 22,1910. Serial No. 573,249.

Structures, of which the following is a full,

clear, and exact description, such as will enable others skilled in theart to which it appertains to make and use the same.

This invention relates to store-fronts, show-windows and similarstructures which clamping members that bear against the outer face of aplate of glass and also against the stationary frame in which the glassis arranged for retaining the glass in position.

One object of my present invention is to provide means of novelconstruction for holding the outside clamping member tightly against theglass and against the stationary frame in which the glass is arranged.

Another object is to provide a glass-retaining means of novelconstruction that exerts an even clamping pressure on the glass andwhich can be set up easily and without liability of cracking or breakingthe glass.

Another object is to provide a novel support for the inside clampingmember which bears against the inner face of the glass, said supportbeing so designed that the inside clamping member can be adjusted toaccommodate glass of difl'erent thickness. And still another object isto provide a glassretaining means comprising an outside clamping member,an arm projecting inwardly from said member beyond the edge of theglass, and a plurality of adjustable devices cooperating with said armfor exerting. pressure on said clamping member in two differentdirections.

Other objects and desirable features of out.

Figure 1 of the drawings is a perspective view illustrating my presentinvention; Fig. 2 is a vertical sectional view taken on approximatelythe line 2 2 of Fi 1; Fig. 3 is a perspective view of one of t esupporting members arranged on the inside of the window opening forsupporting the inside my invention will hereinafter he pointed clampingmember and also the devices which illustrating one of the capsthat arearranged over the joints between the'ends of the outside clampingmembers; Fig. 5 is a perspective view of the. inside supporting memberthat'carries the devices which draw said cap into engagement with theoutside glass-clamping member; 6 is a detail sectional view of anoutside glass-clamping member provided -with an' inwardly pro ecting armwhich is adapted to be engaged by the devices that draw said member intooperative position; and Fig. 7 is a perspective view of a pressed metalkey.

- Referring to the drawin 's" which illustrate the preferred form 0 myinvention, A designates the sill or lower cross-piece of a stationaryframe in which plates of glass B are arranged, said plates beingsupported by blocks or other suitable devices, not shown, such as aregenerally used for this purpose. Outside clamping members C are arrangedin engagement with the outer face of the glass and with the stationaryframe A for retaining the glass in position, and caps or covers C arearranged over the joints formed between the ends of said outsideclamping members G. The outside clamping members C may be of anypreferred shape or design but I prefer to use pieces of molding providedwith vertically disposed flanges 1 and? that project inwardly towardeach other, as shown in Fig. 1, so as to form lugs or stops which metal,pressed or drawn sheet metal, or they can be formed by two pieces ofmolding mitered together. The keys 3 are provided with arms 4 whichproject inwardly beyond the glass, and means is arranged on the in-Specification of; Letters Patent. Paflmnjgfl Nagy, 1%, 1911,

side of the opening which the glass closes for cooperating with saidarms to exert pressure on the outside clamping members in two difi'erentdirect-ions, namely, inwardly against the glass and downwardly againstthe stationary frame A. While I have herein used the terms inwardly anddownward-1y. to,indicate the direction in which the outside clampingmember is moved, it will, of course, be understood that the clampingmember which is arranged at the upper edge of the glass will be drawn inwardly and upwardly, and the clamping members which are arranged at theside edges ofthe glass will be drawn inwardly and sidewise. Therefore, Ido not wish it to be understood that my invention is limited to astructure in which the outside clamping member rests upon the sill orcross-piece of the stationary frame in which the lass is arran ed.

T e means w ich cooperates with the arms 4 on the keys 3 to draw theoutside clamping member inwardly and downwardly consists of a pluralityof adjustable devices cooperating with each arm and mounted in astationary member D that is arranged on the inside of the glass adjacentthe lower edge of the same. These supporting members D which arepreferably formed of cast metal are spaced certain distances from eachother and are securely connected to the stationary frame A. Each of saidmembers D is provided with a vertical wall 5 through which fasteningdevices pass to connect it to the frame A, a lug 6 that projectsforwardly from said verticalwall, ahorizontally disposed flange 7projecting forwardly from the upper edge of said vertical wall, and alug 8 carried by said flange and arranged in alinement with the lug 6.The arm 4 on the key rests on the lug 6, and said arm is provided withan opening 9 which receives a tapered head on an adjusting device 10that is mounted in a screwthreaded openin in the lug 6. Said taperedhead is provide with a slot, as shown in Fig. 1, for receiving ascrew-driver or other suitable tool for turning said device, and anopening 9 is formed in the horizontal flange of the member D inalinement with the device 10 so as to enable it to be gotten at easily.When the device 10 is screwed downwardly the tapered head thereon willbear against the wall of the opening 9 in the arm 4 on the key 3 andthus operate to draw the outside clamping member C inwardly intointimate engagement with the outside face of the glass, the verticalwall 5 of the supporting member D being providedwith a slot 11 throughwhich the inner end of the arm 4 can ass. Means separate and distinctfrom t e device 10 is provided for ex erting downward ressure on theoutside clamping member so as to force it ti htly against the frame A,and in the em odiment of my invention herein shown said means consistsof a screw 12 mounted in the lug 8 on the member Dand adapted to beforced downwardlyinto engagement with the inwardly projecting arm on thekey 3, the lug 8 being so arranged that the screw 12 willbearupon thearm 4 at a point intermediate the key 3 and the inner end of said arm.While I preferfto use the keys 3 for drawing the outside clampingmembers into operative position, I do not wish it to be understood thatmy invention is 'limited to a structure in which keys are used for, ifdesired, the outside clamping member could be provided with inwardlyprojecting arms being lon front ends of the s10ts'13 so as to 4*, asshown in Fig. 6-, for cooperating with the devices 10 and 12 carried-bythe supporting members D. The caps C which are arranged over the jointsbetween the ends of the outside-clamping members are pro- 'vided withinwardly projecting arms 4" supporting members there is not as great aliability of cracking or breaking the glass as there is in structures inwhich the clamping members are subjected to a direct pressure producedby the tightening of a bolt or screw. Another advantage of such astructure is that the outside clamping members are forced tightlyagainst the glass and against the stationary frame in which the glass isarranged so that a tight joint is produced between said members andframe; and still another desirable feature is that the means which drawsthe outside.

clamping members into operative position and holds them in position iscompletely hidden from view. The inside glass-clamping member E which isarranged in engagement with the inner face of the glass rests upon thehorizontally disposed flanges 7 of the stationary supporting members D,said members being so constructed that the inside clamping member E canbe adjusted so as to accommodate plates of glass of different thickness.As 'shown in Fig. 3, the horizontal flange 7 of the member D is providedwith inverted T-shaped slots 13 which'receives bolts 14 that projectdownwardly through openings in the inside clamping member E and havingnuts 15 mounted on the lower ends thereof, said nuts lying in the Theside wide portions of the slots 13. walls of the wide ortions of saidslots prevent the nuts 15 om turning so that the inside clamping memberE can be securely clamped to the supporting members D by insorting ascrew-driver in the slotted heads of the bolts and turning same, theslots 13 enough to permit the bolts to move longltudinally thereof so asto pi'ovide for thick or thin plates of glass. If desired,

the members D can be provided with cover plates 16 which extend over thebottoms and revent displacement ofthe bolts 14 andit e nuts thereon.

Each of the keys 3 which are arranged inside of the outside clampingmember C'is preferably provided with one or more forincense wardlyprojecting legs 3* that bear against the insideof said member C and thushold the key in an upright-or substantially ver;- tical position andprevent it from tilting after it has been inserted in the member C. Saidlegs can be connected to the key in any suitable manner or,"if desired,thekey can be formed from a single piece of sheet metal pressed or drawninto the proper shape, as shown in Fig. 7, the legs 3 and arm 4: beingintegrally connected to the body port-ion of the key.
